Julia Goldsworthy: Twenty-six dolphins died in my constituency in a mass stranding last week, and more than 70 were involved in the incident. In the immediate aftermath, defence spokespeople insisted that the only sonar in use in the area was aboard a survey vessel using a low-powered seabed scanner. This turned out to be a high-frequency sonar, and over the weekend it transpired that Merlin helicopters were also exercising in the area, using a mid-range frequency sonar that has been associated with setation strandings in the past. Can the Minister explain why his Department appears to have issued so many contradictory statements in relation to this incident, and will he commit to full co-operation in an inquiry?
